I would have guessed some sort of emissions meter had you not said "nothing to do with gas"

Hmm...

Or did you mean "natural gas" or "gasoline" by that...

I know, Andy. If it detected one kind of gas and not the other I would have worded that into my response somehow.

True..... it senses things, so I guess you could say it meters its surroundings, but it isn't thought of as a meter in the typical sense of the word. One would not look at this and say, oh-oh...... or, we better adjust this. The word "meter" is not in any part of its name.
